This "stack-breaker" makes it very easy to separate two 2-1/2" pipes. Leak tight and no gasket required. Used on agricultural equipment when you need to remove a stack to get a piece of equipment inside a shed, and in racing when you need a quick take-down method. Solid stainless steel, this assembly consists of two special mating flanges and a quick-disconnect V-band clamp.

Also available in carbon steel for easy welding to standard exhaust pipe.
